This is the best muzzle brake I have ever used/experienced on an AR-platform rifle. I have this brake pinned to the barrel of my BCM 14.5-inch mid-length upper receiver, and it does exactly what it was designed to do; it controls your recoil and your muzzle-drift in all directions. I feel obligated to add however an important note concerning the fact that this brake does absolutely nothing as far as flash-suppression; the muzzle flash from this brake makes your rifle seem like it's firing a 155mm cannon shell rather than a 5.56mm cartridge. Although, this is merely the default nature of having a compensator rather than a flash hider, so this is no real fault of the brake design itself. Ultimately, if you need flash-suppression, this is your worse choice. If flash is no real problem to you, than by all means use this brake and have every single shooter next to you hate you with a fiery passion.

Ordered Monday, received Wednesday :)

Comes with shims, instructions, alignment wheel, warranty card, etc.

Identical to MB556K except for an 1/8th (approx) lip off the back of the device, with a pre-drilled hole for pinning.

The diameter of the lip is almost the same profile as a Noveske N4 profile chrome-lined barrel.

Very pleased with BCM on their timeliness in shipping, and SureFire with their product.

Although, getting an actual product photo may be helpful to future customers.
